Referring now to Figure 2, it will be observed that the spring hangers are each provided at each end thereof with transverse grooves and are firmly secured to the center of the leaf springs by means of U-bolts as indicated at 59 and 60, which rest in the grooves and at their lower ends pass through apertures in plates, one of which is indicated at 61, the springs being compressed between the spring hangers 58 and the plates 61 by nuts 62 and 63 screw threaded upon the ends of the U-bolts 59 and 60.
Referring to Figure 3, it will be observed that the threaded studs 56 have each a tapered portion fitting in the corresponding tapered aperture 55 in a projection 54 and are secured in the apertures by means of nuts one of which is indicated at 65 bearing against brake dust covers secured to the sides of the members 43 and 44 and that the spring hangers 58 are pivotally mounted upon the portions of the members 56 which project beyond the sides of the members 43 and 44 opposite the nuts 65, the projecting portions of the studs being provided with relatively coarse screw threads as indicated at 66. Cup shaped members one of which is indicated at 68, adapted to contain lubricant, are secured to the spring hangers 58 over the ends of the studs 56, and a resilient washer as indicated at 69 surrounds each stud 56 between the spring hanger and the adjacent surface of the pivoted arms to provide a lubricant seal. The springs 45 are provided at each end thereof with eyes as indicated at '70 and 71 inFigure 2 and spring shackles shown at '72 and 73 respectively connect these eyes with apertured brackets '14 and 75 secured to the lower surfaces of the frame side members 11 and 12. Referring to Figure 3, a sleeve member as shown at 77 is formed integrally with the wheel carrying end 53 of each of the arms 43 and 44, these sleeves being provided internally thereof with annular ribs as indicated at '78 in the ends thereof adjacent to the corresponding ends of the members 43 and 44, and with screw threads as shown at 79 intermediate their lengths. Astubaxle 80 to which one of the wheels 40 or 41 is rigidly secured by means of a hub, one of which is shown at 82, projects axially through each sleeve '77 and is journaled therein by means of outer roller bearings and inner roller bearings 86. The outer roller bearings 85 each comprise an outer race 88, the inner side of which abuts against an annular ring member 89 adjustably secured in each sleeve '77 by means of the screw threads '79 and corresponding screw threads upon the exterior surfaces of the ring members. Each outer roller bearing 85 further comprises an inner race member 90 mounted upon the corresponding stub-axle 80 and restrained from axial mo-.
tion in one direction thereon by means of an annular shoulder 91 formed on the stub axle. Bearing rollers 92 are disposed between the outer race member 88 and the inner race member 90. The inner; roller bearings 86 each comprise an outer race member indicated at 94 abutting at its outer side against the corresponding annular rib '18, an inner race member 95 mounted on the corresponding stub-axle 80, and rollers 96 interposed between the inner and outer race members. A cylindrical spacer 98 is disposed, surrounding each stub-axle 80, between the corresponding inner race members 90 and. 95 and a flanged sleeve spacer 98. A nut 102 is threaded upon the inner end of each stub-axle 80 and tends to move the stub-axle relative to the spacer member 98, the inner race 95 and the sleeve member to tighten the roller bearings 85 and 86. Oil seals 103 and 104 aredisposed at either end of each sleeve 77 between the sleeve and the corresponding hub 82 and the sleeve and the member 100 respectively. A brake cover plate indicated at 105 is secured to each of the members 43 and 44 by means of stud bolts 107 and the studs 56 and serves to support anchoring and actuating means, not shown, for the brake bands 109 operatively mounted within the brake drums 110. A driving axle 112 is operatively connected with each stubaxle 80 by means of universal joints 114 and the flanged members 100.
As particularly illustrated in Figures 4 and 5, the members 43 and 44 are tubular members and the tubular construction thereof is extended through the ends 53 as illustrated at 115.
Referring now to Figures 1, 4, 5 and 6, it will be observed that tubular sleeves and 121 are mounted upon the cross member 15 adiacent to the ends thereof. Each of these sleeves comprises 100 enlarged end portions indicated at 122 and 123 in Figure 4 connected by a somewhat reduced center portion indicated at 125. Rubber bushings 127 and 128 are disposed between the enlarged portions 122 and 123respectively of each sleeve and 105 the cross member 15 and are bonded both to the sleeves and to the cross member. The ends of the members 43 and 44 are each provided with a half bearing .indicated at 130 in Figure 5 which fits about one half of the reduced portion 125 of the no corresponding sleeve 120 or 121. The bearing caps 50 are each provided with a corresponding half bearing indicated at 132 in Figure 5 which fits about the remaining half of the central portion of the tubular sleeve and forms a-bearing by 115 means of which the members 43 and 44 are journaled upon the sleeves 120, and 121. In the construction shown, a ridge 135 is provided on the portion 125 of each sleeve and these ridges fit into grooves, one of which is indicated at 137, provided in the half bearings 130 to prevent rota- .tion of the members 43 and 44 relative to the sleeves 120 and 121, whereby relative motion of the members 43 and 44 and the cross member 15 will be taken up by the elasticity of the rubber bushings 127 and 128. The bearing caps 50 are secured to the members 43 and 44 by means of stud bolts indicated at 51, and strengthening ribs 139 are provided on the bearing caps to increase the rigidity thereof. Bosses 140 are formed at spaced intervals on the members 43 and 44 and are apertured and screw threaded internally to receive the screw threaded ends of the bolts 51. From this description it will be observed that the wheels 40 and 41 are maintained in alignment with the chassis frame by the rigid, pivoted arms 43 and 44, but that vertical motion of the wheels on an arc, the radius of which is one leg of a right triangle, the hypotenuse of which is the member 43 or 44, is permitted by the elasticity of the rubber bushings 127 and 128. This vertical re wheels is resiliently resisted by the iich support the chassis frame upon The slight lateral motion of the springs r the wheels.
wheels due to the arc of the members 43 and 44 is taken care of by the shackle connections '72 and 73 at each end of each spring 45, and the longitudinal component of the road shocks imparted to the wheels are absorbed by the rubber bushings 12"! and 128 as the center portions 125 of the sleeves 120 and 121 are spaced from the Power is transmitted to the rear wheels from the differential 28 by means of the driving axles- 112, and motion of the wheels relative to the differential is taken care of by the universal joints 114 and the telescopic sections 145 in the axles 112..
From this description it will be observed that I have provided an individual spring suspension for the rear driving wheels of an automotive vehicle by means of which the wheels are firmlyconnected with the chassis frame and rigidly maintained in alignment therewith and at the same time both the longitudinal and vertical components of road shocks imparted to the wheel are effectively absorbed before reaching the chassis frame.
While, for the sake of simplicity, the construction has not been shown in this illustration, it is obvious that rebound dampeners or shock absorbers may be effectively interposed between the chassis frame and the wheels to dampen the rebound and improve the riding characteristics of the vehicle.
